PCPP Loading Boxes - Update

Had to rework the SVG elements to solve some IE bugs so that gave me the opportunity to redo the cube elements so that they more closely match the new PCPP brand. Plus, these look much more 3D.

And they remind me of the art in Crossy Road, which makes me smile.

I also updated the shadow SVG to remove the clipped corners in the previous version.

You guys should see how this looks on the new site. :)
